Lacto-fermented Pink Lemonade!

I love the lacto-fermented ginger ale recipe on Instructables, but I was out of ginger. So I omitted the ginger, doubled the lemon juice, and substituted maple syrup for the honey. Just one small problem, though. The whey was moldy! What was I to do? I decided to just dilute it and not ferment, but then it came to me - homemade beet kvass! It wasn't moldy and it had good bacteria, but the best part was that it made PINK lemonade! You can't even taste the beets, since it is only 2 tablespoons. Here is the recipe:
1/2 cup lemon juice
1/4 cup honey or maple syrup
1/2 tsp sea salt
2 tbsp whey OR beet kvass for pink color
1 quart water
Mix all ingredients in a quart mason jar (or bottle, I suppose) and let ferment for 3 days. This is very strong, both sweet and sour, so dilute it 50/50 with water. Enjoy!
Note: I do not like this as much as the ginger ale!
